Liquid Copper Fungicide is a copper fungicide garden spray that controls many diseases attacking citrus, fruits, nuts, vegetables and ornamentals. It is very weather resistant and sticks to the plant or woody surface once it’s dried, providing long lasting control. Use as a dormant spray on fruit trees, a foliar spray on citrus, and as a foliar spray on vegetables, ornamentals, conifers, trees, and shrubs to control various foliar diseases. As a dormant spray, it can be mixed with insecticide oil (such as our Horticultural Oil) to give a good combination treatment.
The control of diseases with fungicides is based on PREVENTION. Plant surfaces must be completely covered with the fungicide to successfully prevent infection. Copper pesticides are considered preventative, not curative of plant diseases. Use the highest indicated rate when disease incidence is high or expected to be, depending on rainfall and temperature. The lower rate is suitable for general preventive sprays under normal conditions. Since weather conditions and disease incidence vary, consult your Agricultural Extension Service for timing and initial application.
Liquid Copper Fungicide Instructions
Apply 2-4 tablespoons to 1 gallon of water and spray thoroughly. For deciduous trees, apply a fall application and then again just before bud break to control peach leaf curl, shot hole, brown rot and other diseases. To control foliar diseases on vegetables and ornamentals, apply prior to disease appearance and control at two week intervals. See label for specific application rates.
